Be it known that I, ROBERT H. ELSEY; a citizen ofi the United States, 'residing at Coalinga, in the county of- Fresno, State of (lalifornia, have invented `certain new and useful Im rovementsinEqualizing Multiple Air-Lifts` for Deep-Well Pumping; and I; do declare .thejfollowing to be a. full, clear, and exact description of thesame, such as will enable others skilled-in the art 'to which it appertains'to make and use the same, reference being had lto the-accompanying drawings, and to the characters of reference marked thereon, which form a part of this a plication.

lhis invention relates to improvements 1n jineans for deep well pumping and particularly to that class of umping mechanism known as air lifts, the o ject of the'inventinbeing thereby lifting the uid easily to the surface to roducelan air liftfor deep wells'whichl equalize and multiply the air lpressure according to the'submergence `of t e Huid,

of the ground with a mininum of expense and power; also to provide a simple and easily constructed device. for 'the purpose.. By

"equalizing and multiplying the air pressure .l ,according to the submergence of the iuid is.

.from the meant that I aimto have the airpressure Y"discharges spaced in mltipledistances apart such distances" being determined from` the being adalpted to carry .t e liqpid ldpward ighest point to whic lit is lifted by the pressure discharges below. This o je ct Laccomplish by means offa fluid tube,` vor casin into which are insertedfcompressed.

In; the drawings similar characters of reference indicate correspondingparts in the' cation and severalviews,

Figure 1 1s. a. cross section ofA a well and, fluid ftube showing my complete apparatusj installed. therein'. g, Fig. 2 is a vertical sec tional view of a tube and air lift mechanism.

Y. Referring nowmore lparticularly to the li uid from the s for the Huid, said-lifts .pressure of the air second tube raises the uid to thenext tube `and so on until the liuid reaches the surface characters of reference' on the drawings 1 designates the well `and 2 the iiuid tubeor 2 are a plurality' of holes 3 through `which the liquid enters the said tube- 2,Y these holes being ladditional feeders abovey the main suction at the bottoni. y

Disposed in the sides of' the tube 2 at space -4 extendin from the inside to the outslde of the said tu e2 and projecting in an u ward direction. Into the outer ends o said joints 4 are screwed air su ply pipes 5 projecting to the top oftheweil. l p Into the inner ends of the joints 4 are screwed tubes 6 having vtop caps 7 in which tubes are provided aplurality of air discharge holes 8 spaced apart at intervals for vthe urpose as will appear, over which holes are sposed sleeves 9 spaced from the tubes 6 and closed at their upper ends and ,open at their lower ends.

The device is particularly designed "for oilV huid to ralse it to the surface of the ground.

The lower tube 6 always extends into the bittom to the surface of the su mergence an i' the air lifts 8-9 are spaced a desired distance a art to lpro erl e ualize the pressure accor to t e dbpt o 'submergence, the intake oles 3 4belng always .between the first and second lifts SQ-Qfthat is the distance between the lifts distances are return elbow joint pipes' vcasing therein, in -thebottoni of which casing 8"-9 is determined according to the liquid I to belifted, and the distance 4it must be lifted, each lift being so disposed as to carry the li uid on u ward from thehighest point it is li ted b t e'lifts below. The air pressure in the4 ifts 8-9 raises they-fluid in the tube 2 to -the next tube 6 above, when the from the lifts 8-9 in said In. wells where the submers'ion equals fully fifty per cent. of thedepth o1' over, tWo of the tubes 6 end air tubes 5 will be used, and Where the submersion is Yless than fifty per cent. of the depth then three or more of the tubes having the air lifts may be used, the principal aim being to equalize the pressure es described.

From the foregoing description it will be readily seen that the invention embodies such features as substantially full the objects of the invention as set forth herein, vizz-to roduce e multiple air lift-e ualizing and multiplyingfessure system for dele well pumping, annlwhich will eliminete bec pressure.

While this specification sets forth in detail the present and preferred construction of the device, such deviations from such e1 Lese What I c aim as neveT and useful and desire` to secure by Letters'Petent is AAn air 'hft for deep Wells comprising e casing, an air tube therein lisiving air holes at spaced intervals thereon, sleeves disposed over seid holes and s toed from seid tube, end means for supplying air pressure to said tube, es s'et forth.

In testimony whereof affix my signature in presence of two Witnesses.
